This invention relates to furnace fronts of the type adapted for oil. burning or solid fuel burning, and comprising a front plate and a back plate between which are formed valve-controlled lateral air openings, a deflector adapted to direct the air entering the lateral openings toward the furnace, and an oil burner passing through the deflector and arranged substantially centrally of the stream of air directed thereby.

The invention is illustrated by way of example in the accompanying drawing in which Fig. l is a verticalsection, Fig. 2 a

' horizontal section, Fig. 3 a section at right angles to Fig. 1, and Fig.4 an elevation.

The improved furnace front shown comprises a front plate 1 and a baclr plate 2 and a lateral wall 3 connecting said plates and having valve-controlled lateralair openings 3. Installed between the plates 1, 2' is a deflector 4: adapted to direct the air entering the lateral openings 3 towards the'fur nace, and passing through the deflector is an oil burner 5 which is arranged substantially centrally of the stream of air directed by the deflector.

For controlling the lateral openings 3 there are provided butterfly valves 6 which are adapted to swing on vertical axes and Specification of Letters Patent.

are interconnected by cranks 8 and a connecting rod 9. One valve is fitted with a bevel wheel 10 meshing with a mutilated bevel wheel 11 rotatable by a handle '11 whereby the valves may be operated in unison.

The deflector is constituted by contiguous curved plates which are dished in their mid-portions at 12 to accommodate the oil burner 5.

If desired, the valves may be separately operable.

13 denotes a door facilitating removal of carbon from the furnace.

I claim A furnace front comprising a front plate, a back plate, a cylindrical lateral wall connecting said plates and formed with two diametrically opposite air openings, two connerted valves controlling said openings, said valves being mounted to swing on vertical axes, a deflector comprising two contiguous curved plates dished in their midportions, the abutting faces of said plates being in a vertical plane, said deflector being adapted to direct air entering said openings, and an oil burnersupported by said front plate and passing between the dished mid-portions of said deflector.

"In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
